Q: Driver's seatbelt not locking into place

That problem is usually caused by the buckle on the right side of the seat. Look very closely down inside of it to see if something fell in, such as a coin. Some buckles are “pretensioners”, which means that they tighten upon airbag deployment; this is an option on your model. Pretensioners are relatively expensive to replaced, so you may want to look into the used market, if replacement is required. I recommend having a certified technician, such as one from YourMechanic, come out to your car’s location to run a diagnostic inspection of your malfunctioning seatbelt, and suggest the best path to repair.
